摘　　要：主要从热化学水解制氢、太阳能-天然气重整制合成燃料、太阳能、煤气化制合成气,以及利用太阳能裂解其他含碳燃料和控制CO2排放等方面,简要评述了太阳能热化学燃料转化技术的发展现状及难点及发展趋势。概述了将聚集的太阳能热能向化学燃料的热化学转换过程的最新发展动态。这个转变实现了太阳能的储存,同时使得太阳能可以从太阳能丰富的地区运输到太阳能缺乏但人口密集的地区。This paper reviews the recent developments of studies of thermochemical conversion of concentrated solar thermal energy to chemical energy. The conversion has the advantage of producing long term storable energy carriers from solar energy and enables solar energy transportation from. the sunbelt to remote population centers. The thermochemical conversion pathway is characterized by a theoretical high efficiency. However, there are special features in solar processes in comparison to conventional thermochemical processeshigh thermal flux density and frequent thermal transients because of the fluctuating and intermittent insolation-and conventional industrial thermochemical processes are generally not suitable for solar driven processes. Therefore, the adaptation to such features of solar thermochemical processes has been an important R＆D task in this research field. Thermochemical steam or CO2 gasification of coal, steam or CO2 reforming of methane, and splitting of fossil fuel, are industrially important endothermic processes to produce useful chemical fuels such as hydrogen, synthesis gas and C2-hydrocarbons, which have been considered as solar thermochemical processes. The technical difficulties and potential to conduct these endothermic processes by utilizing concentrated solar radiation as the process heat are recommended here. A low temperature solar thermochemical power plant with inherent CO2 recovery using methanol-fueled chemicallooping combustion is also given.
